Mandriva Linux Security Advisory : mariadb (MDVSA-2013:102)
High Nessus Plugin ID 66114
SynopsisThe remote Mandriva Linux host is missing one or more security updates.
DescriptionUpdated mariadb packages includes fixes for the following security vulnerabilities :
Unspecified vulnerability in the MySQL Server component in Oracle MySQL 5.5.26 and earlier allows remote attackers to affect integrity and availability, related to MySQL Client (CVE-2012-3147).
Unspecified vulnerability in the MySQL Server component in Oracle MySQL 5.1.64 and earlier, and 5.5.26 and earlier, allows remote attackers to affect confidentiality, integrity, and availability via unknown vectors related to Protocol (CVE-2012-3158).
Multiple SQL injection vulnerabilities in the replication code in Oracle MySQL possibly before 5.5.29, and MariaDB 5.1.x through 5.1.62, 5.2.x through 5.2.12, 5.3.x through 5.3.7, and 5.5.x through 5.5.25, allow remote authenticated users to execute arbitrary SQL commands via vectors related to the binary log. NOTE: as of 20130116, Oracle has not commented on claims from a downstream vendor that the fix in MySQL 5.5.29 is incomplete (CVE-2012-4414).
Stack-based buffer overflow in the acl_get function in Oracle MySQL 5.5.19 and other versions through 5.5.28, and 5.1.53 and other versions through 5.1.66, and MariaDB 5.5.2.x before 5.5.28a, 5.3.x before 5.3.11, 5.2.x before 5.2.13 and 5.1.x before 5.1.66, allows remote authenticated users to execute arbitrary code via a long argument to the GRANT FILE command (CVE-2012-5611).
A buffer overflow that can cause a server crash or arbitrary code execution (a variant of CVE-2012-5611)
Heap-based buffer overflow in Oracle MySQL 5.5.19 and other versions through 5.5.28, and MariaDB 5.5.28a and possibly other versions, allows remote authenticated users to cause a denial of service (memory corruption and crash) and possibly execute arbitrary code, as demonstrated using certain variations of the (1) USE, (2) SHOW TABLES, (3) DESCRIBE, (4) SHOW FIELDS FROM, (5) SHOW COLUMNS FROM, (6) SHOW INDEX FROM, (7) CREATE TABLE, (8) DROP TABLE, (9) ALTER TABLE, (10) DELETE FROM, (11) UPDATE, and (12) SET PASSWORD commands (CVE-2012-5612).
MySQL 5.5.19 and possibly other versions, and MariaDB 5.5.28a, 5.3.11, 5.2.13, 5.1.66, and possibly other versions, generates different error messages with different time delays depending on whether a user name exists, which allows remote attackers to enumerate valid usernames (CVE-2012-5615). Be advised that for CVE-2012-5615 to be completely closed, it's recommended to remove any anonymous logins. Previously, such a user without access rights was added by default.
A vulnerability was found in the handling of password salt values in MySQL. When a user logs into MySQL a salt value is generated that is then used to prevent password guessing attacks (since the salt value must be known in order to send a password). This salt value is created at the start of a session and used for the entire session, once authenticated an attacker can use the MySQL change_user command to attempt to login as a different, as the salt value is known a password guessing attack will be much more efficient (CVE-2012-5627).
in addition it fixes MDEV-4029 and rpl.rpl_mdev382 test from mariadb-bench, and a problem preventing the feedback plugin from working has been corrected.
SolutionUpdate the affected packages.
